There was an NHL player some years ago who was rushed to the hospital after he collapsed during the pre-game warmups showing signs of a cardiac episode. He was OK, but the doctors told him he had to change one bad habit of his. One game days, he drank SEVENTEEN cups of coffee in the hours before the game. WTF?
I used to measure the amount of coffee I drank a day, when I counted it, in pots of coffee. It amounted to something like 20 or more cups a day.
I’m down to four in the morning now. A little less wired. It never did affect my sleep though.
